Nectarine tree named &#39;Honey Spring&#39;

ABSTRACT

A new and distinct variety of nectarine tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:
         1. Vigorous, upright tree growth.   2. Regular and heavy production of large size fruit.   3. Fruit with firm, yellow flesh, good handling and shipping qualities.   4. Fruit with very good flavor.   5. Fruit with attractive red skin color.

BOTANICAL DESIGNATION

Prunus persica var. nucipersica

VARIETY DENOMINATION

‘HONEY SPRING’

BACKGROUND OF THE VARIETY FIELD OF THE INVENTION

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricot, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of nectarine tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, California.

PRIOR VARIETIES

Among the existing varieties of nectarine trees, which are known to us, and mentioned herein, ‘Honey May’ Nectarine (U.S. Plant Pat. No. #19,363) and our proprietary nectarine selections ‘387LU177’ ‘58ZA720’ and ‘396LN445’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

A new and distinct variety of nectarine tree (Prunus persica var. nucipersica) was originated by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling from our proprietary nectarine seedling with the field identification number ‘387LU177’. The seed parent (387LU177) originated as a first generation seedling from a cross between our proprietary seedlings with the field identification numbers ‘58ZA720’ and ‘396LN445’. A large group of these open pollinated seedlings were planted and maintained on their own root system, during which time we recognized the desirable tree and fruit characteristics and selected it in 2007 for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of nectarine tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE NEW VARIETY

The present new variety of nectarine tree is of large size, vigorous, upright growth and a productive bearer of large size, yellow flesh, clingstone fruit. The fruit is further characterized by having firm flesh, very good flavor and eating quality, with an attractive red skin color. In comparison to its seed parent (387LU177) the fruit of the new variety is firmer, larger in size and is approximately 15 days later in maturity. In comparison to the commercial nectarine ‘Honey May’ (U.S. Plant Pat. No. 19,363) the fruit of the new variety is larger in size and is approximately 30 days later in maturity.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new nectarine variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Any variety or selection     observed during indexing of plant characteristics with abnormal     fungus, bacterial, virus or insect susceptibility is destroyed and     eliminated from our breeding program. The present new variety of     nectarine tree, its flowers, foliage and fruit herein described may     vary in slight detail due to climate, soil conditions and cultural     practices under which the variety may be grown. The present     description is that of the variety grown under the ecological     conditions prevailing near Modesto, Calif.
